Patent FI-962562-A (FI)
Inventor: KIRLA OLLI
IPC: H04M1/60
Filed: 1996-06-19
Abstract: The invention relates to an acoustic echo suppressor and a non-linear processor for an echo canceller in a 4-wire data transmission network. An echo canceller is typically controlled by comparing the power levels of the near-end and far-end signals. The transfer function of an acoustic echo path is usually very non-uniform. According to the invention, the spectrum of the far-end signal is treated, before the signal power level is calculated, with a weighted filter, which models the effect of the transfer function of acoustic echo. As a result, the double talk dynamics is improved, since high-energy vowels of far-end speech, which normally cause low-energy vowels of near-end speech to be clipped in an echo suppresseor, will be attenuated.

Title: Submarine detection by ultrasonics - is based on measuring phase difference between two signals received from target
IPC: G01S15/42
Filed: 1956-10-24
Granted: 1975-02-28
Abstract: The device indicates the position of a target in particular of a submarine using ultrasonics. A dual input receiver (2) receivers on two distinct channels the signals coming from the target, e.g. echoes of pulses reflected by the target. The instantaneous phase difference between signals received by the two channels is measured and used to determine the orientation of the target. An oscilloscope tube (6) is used to display the information. Range information is applied to one set of plates and phase difference information to the other.

Abstract: 225,087. Linen Industry Research Association, and New, G. F. Jan. 15, 1924. Yarns and threads, testing. - Comprises a machine whereby a plurality of specimens may be simultaneously subjected to a rubbing or rubbing and bending test and whereby a predetermined number of rubs or rubs and bends may in a given time be given to the specimens under a given tension. The machine comprises a panel 1 on which the threads 2 to be testea are arranged vertically their upper ends being clamped to an adjustable bar 3<a> while the lower ends are connected to and tensioned by lengths 4 ot squared rod guided in square holes in a plate 5, thus preventing the threads from untwisting. The rubbing device comprises three rows 8<a>, 8b, 8<c> of hardened steel pegs bolted to a metal plate 8. The middle row of pegs are shown in alignment with the outer rows, but if desired they may be set out of alignment to increase or decrease the rubbing. The plate 8 is reciprocated by a balanced crank 9 and a counter 10 indicates the number of reciprocations of the rubbing plate. This number may bd recorded by the device shown in Fig. 4. A ratchet wheel 12 is moved step-bystep through pawls 13, 14 from a cam 15 and advances a drum 11 on which rest markers 17 which when the weights 4 drop due to a thread breaking take the position shown in dotted lines. Instead of the clamps 3 shown, the thread may be passed from the weight 4 over top guide rollers to a counterweight. A spring clamp grips the thread at the top and is held closed by a catch which is released when the thread breaks, the thread being pulled away by the counterweight. The motor circuit is provided with a mercury switch and when any of the weights 4 drop on to a bar 27 the switch breaks contact.

Title: Safety trip valve for gas or steam turbines
IPC: F16K1/00
Filed: 1976-01-14
Abstract: 1503243 Valves TURBODYNE CORP 14 Jan 1976 [19 June 1975] 01435/76 Heading F2V [Also in Division G3] A safety trip valve for interrupting the flow of working fluid to a turbine, is automatically closed on the occurrence of adverse working conditions (see Specification 1,281,408) but cannot re-open when the adverse conditions are corrected until an auxiliary valve is actuated by mechanical means. The valve is shown in its normal operative position permitting fluid flow from inlet 23 to outlet 25. Adverse conditions cause a lever 13 to open a pilot valve 11 and vent a chamber 42 below piston 34 via line 12 and adjustable throttle 14. This causes the main valve 33 to be moved into engagement with its seating 27 by inlet pressure communicated to the chamber above the piston 34 via orifice 68 and passages 67, 69, 71. Once the main valve is seated the orifice and passages instead communicate with the outlet but the chamber above the piston still receives inlet pressure fluid via an exposed port 50, passages 48, 49 and passages through auxiliary valve 56 which is then forced open by the incoming fluid pressure. The main valve is maintained in its closed position even if the pilot valve 11 is subsequently closed causing the chamber 42 to be re-pressurized via clearance 39, because the lower surface of the main valve 33 is still only subjected to outlet pressure. Thus it is necessary to screw-down rod 80 sufficiently to engage and close the auxiliary valve 56, causing the upper chamber to bleed down to outlet pressure via orifice 68 and passages 67, 69, 70 and thereby create sufficient pressure differential across piston 34 to overcome the oppositely-acting pressure differential across the main valve 33. However, the main valve can only open at the rate allowed by the subsequent upward movement of the abutting rod 80 thereby providing a controlled re-opening. The adjusted rod 80 can be used to locate the main valve in any position intermediate its closed and fully open positions without detriment to the safety functioning of the valve.

Abstract: 1377802 Rotary positive-displacement engines A TAKACS 12 Jan 1972 1503/72 Heading F1F In an I. C. engine main rotors 30, 50 and a single-lobe valve-rotor 76 are disposed in intersecting parallel chambers 20, 22, 23 and spring- loaded strips 133, 141 permanently abut the main rotors, gears 46, 66, 79 fixed to rotor shafts 32, 52, 78 being inter-connected by idler gears 99, (100), Fig. 4 (not shown), so that all of the rotors revolve clock-wise with the main rotors 90 degrees out of phase with each other and turning at half the speed of the valve rotor. The load is coupled to the shaft 52. An ignition distributor 112 is driven by the gear 99. Fuel-air mixture inducted through each of bores 116, 124 is compressed by the adjacent main rotor into the portion of the chamber 23 into which the lobe of the valve rotor passes, ignition being effected by a corresponding spark plug 109 or 110. The combustion products pass into the chamber 20 or 22 containing the other main rotor and drive the latter until permitted to escape through a bore 117 or 128. Channels 137, 145 prevent exhaust gases being trapped between the strips and main rotors. Scavenging is effected by the incoming mixture while the rotors are in positions allowing direct communication between the bores 116, 128 or 117, 124, Figs. 7 and 10 (not shown). Induction is aided by negative pressure produced in the working space between each strip and the adjacent bore 116 or 124. Other embodiments, Figs. 11 to 18 (not shown), differ mainly in that they have two or three main rotors of various shapes co-operating with a single valve rotor having one or two lobes to suit the shapes and numbers of the main rotors. The engine may be modified such that fuel is injected into the working spaces.

The inner duct is defined by inner wall 15 and intermediate wall 12 while the outer duct is defined by outer wall 11 and intermediate wall 12. The wall 15 terminates in a tailcone 16, the wall 12 terminates at 32 and flap members 33 are pivotally mounted thereon at pivot points 35. A shroud member 23 is mounted on the outer wall 11 for axial movement so as to define with the tailcone 16 a variable area nozzle. The shroud is movable by actuators 31 acting through screw rods 25 and recirculating ball-type nut members 26 fixed at the forward end of the shroud. The screw rods are mounted at their rearward ends in bearings 24 secured on the shroud. The flap members 33 are of double wall form comprising inner wall 34 and outer wall 37, one flap being shown in full lines in its radially outer position in which it blocks the fan air passage 21, and in broken lines in its radially inner position in which it abuts the tailcone 16 to block the turbine exhaust gas flow passage 18. The flaps are free-floating in dependence on the pressure in the passages; the flaps may alternatively be mechanically adjusted. The walls of each flap member are inter-connected by linkage as shown.
